Answer:
B) { 51, 149, 140 }
C) { 16, 63, 65 }
Step-by-step explanation:
We need to choose Pythagoras theorem formula 

now, we can verify each options 
option-A:
a=1
b=1
c=1
now, we can verify formula 


We can see that left side is not equal to right side
so, this is FALSE
option-B
a=51
b=140
c=149
now, we can verify formula 


We can see that left side is  equal to right side
so, this is TRUE
option-C
a=16
b=63
c=65
now, we can verify formula 


We can see that left side is  equal to right side
so, this is TRUE
option-D:
a=6
b=8
c=11
now, we can verify formula 


We can see that left side is not  equal to right side
so, this is FALSE
 
        
                    
             
        
        
        
What aboout it? please clarify.
        
                    
             
        
        
        
Plug in 0.9 for x
-(x) + 2.7
- (0.9) + 2.7
simplify
2.7 - 0.9 = 1.8
1.8 is your answer
hope this helps
        
                    
             
        
        
        
Pi r2
17 divide 2=8.5 
Then 
8.5•8.5=72.25
Then
3.14•72.25=226.865
Then 
226.865 divide by 2 =113.4325m2
        
                    
             
        
        
        
Answer:
-480
Step-by-step explanation:
If f varies directly as g, and inversely as h, then we can write the variation equation:
 , where k is the constant of variation.
, where k is the constant of variation.
If g=56 when h=-2 and f=-7, then we substitute these values into the formula to find the value of k.



The equation now becomes:

if f=10 and h=-12, then;


The correct answer is B.
